PURPOSE:To cool a heat emitting component even when an oven is in service and enable stable use of induction heating by furnishing a blower fan and a wind duct in the oven, and inhaling the exhaust air given out of a spout hole to the wind duct from an aux. suction hole. CONSTITUTION:When heating is started by an operational part 3, a control circuit 25 drives an induction heating coil 8 or a heater 22. A heat sink 18 on which a switching element 19 as a heat emitting component is mounted, is cooled by the wind from a main suction hole 16 generated by a cooling fan 17. If therein an oven situated below 10 is in service, hot air is exhausted from the exhaust hole 11 being willing to be included in the suction air for the fan 17. Now a blower fan 12 inhales the exhaust air from an aux. suction hole 14, and it is allowed to pass through a wind duct 13 to prevent the exhaust air from the oven 10 to be included in the suction air for the fan 17. Whereby the heat emitting component can be cooled even when the oven is in service, and stable induction heating can be made. |
